Procedure
4.33 g (9.41 mmol) of 3,3-diphenylpropyl 4-(3-benzyloxypropoxy)-3-oxobutanoate was hydrogenated in the presence of a catalytic amount of 5% palladium/carbon in 50 ml of ethanol under 5 atm. for 14 days. After an ordinary after treatment followed by the purification by the silica gel chromatography (hexane/ethyl acetate=1/1), the title compound was obtained.
